That system will throw you all kinds of curve balls if the fuel pressure is borderline low BTDT got the T-shirt. Yours fits the bill with all the symptoms of a pump that is borderline.
KOEO (key on engine off)
KOER (key on engine running)
KOEO fuel pressure 65 PSI its regulated at 65 and could make 100 if not regulated.
KOER 55 to 60 nuttin less than 55 at idle. NOW the kicker and what you need to focus on,,, anytime you apply throttle the fuel pressure should go to 65 and stay there under any load no mater how small are how big. If it can not maintain 65PSI under a load the pump is not able to supply enoufh fuel to the engine under those conditions. Your MAF will be under reporting for the conditions, the O2's will be driven lean and it may show multiple misfires. A tip may be its a dog under full acceleration it may pop back thru the intake. Another tip is it is slow to start but starts as soon as you let off the key. And of course it may not start at all intermittently.
If its a pump make sure the tank is clean no rust spots anywhere including the most over looked place THE UNDERSIDE OF THE TOP OF THE TANK. That one may be plastic it needs to be clean also.
